The Water/Methanol injection has been in use for several decades in multiple applications.  Originally, it was used to reduce knock while increasing power and performance in aircraft engines.  Eventually, it came to be used in the motorsports industry where it was found to have substantial benefits on turbocharged engines.  The Weistec Water/Methanol injection System features a Water/Methanol Controller with built-in MAP sensor.  This controller is a progressive controller that slowly increases injection as boost builds, resulting in a smooth and seamless operation.  The included Turbo Charge Pipes each have a built-in bung, allowing the use of two injectors for uniform injection and cooling.  The combination of the cooling effects of methanol and the knock resistance of water results in significant gains in horsepower* and torque* as well as a reduced chance of heat soaking the intercooler system.

This system is a complete, bolt-on system that can be installed without any guesswork or custom fabrication.  Weistec has engineered and manufactured many of the components of this system to ensure a simple and straightforward installation. The gains in performance and consistency make this system an essential upgrade for the McLaren Twin Turbo V8 engine.
